LPM 4200 Loop Power Indicator

Large 1" Digit Loop Powered Process Indicators

The large digit loop powered indicators is designed for areas where a local readout of a particular process variable is required and ease of viewing is important. Powered by the 4 to 20 mA loop, these meters drop only 2.7 Volts from the loop being monitored and can be scaled to readout directly in the engineering units desired.
